SendVia Changes SMTP Servers On the Fly [Downloads]

Thunderbird only (Windows/Mac/Linux): Experimental Thunderbird extension SendVia changes your outgoing SMTP mail server on the fly while composing a message.

Using the extension is as simple as opening a new message window and selecting your SMTP server from the list, or adding a new one on the fly with the handy New SMTP Server item, which saves to your account settings for next time—a feature the more well known SmtpSelect extension doesn’t have. This extension is useful for anyone that moves their laptop around, as SMTP servers are often blocked by internet service providers to combat spam, and taking a trip to account settings each time is a serious annoyance.

SendVia is a free experimental add-on (meaning you will need a username and password to download it from Mozilla Add-ons). For more useful tweaks for your email experience, see Gina’s list of 8 killer extensions for Thunderbird.

CrunchBang is a Speedy, Dark-Themed Linux Desktop [Screenshot Tour]

CrunchBang, an Ubuntu-based Linux distribution that sports a snappy, low-drag interface and is perfect for thumb drives, live CDs, or speed-obsessed Linux fans. Check out how it looks and runs in our screenshot tour.

Getting started is pretty simple. Head to CrunchBang’s main site, find the Download section, and grab the main ISO file (from BitTorrent or directly). You can burn it to CD/DVD, load it as a virtual system in VirtualBox/VMWare, or install it on a flash drive with UNetbootin. Put your CD or USB drive into your system, or boot your virtualization tool, and hit Enter at the boot prompt to load the live session of CrunchBang.

The first thing you’ll notice is that the default CrunchBang desktop is fairly sparse and almost entirely themed around dark grays and black. There is, however, a pre-loaded Conky on-screen display in the upper-right corner. A full desktop shot is below; click to get the non-thumbnailed full view:

Conky is one of those Linux tools that gets better every time you open it up and poke around. The basic setup in CrunchBang is pretty functional, giving you a list of the (really helpful) Windows key shortcuts (it’s called the “Super” key in Linux land) and basic system stats. You can, of course, modify a single text file to customize Conky for ambient productivity, or try out a pre-configured setup out there, like this beautiful, minimalist setup well-liked by readers.

You might boot up with a lower resolution than you’d like, or (more likely) notice that your keyboard is set up for UK fingers. Everything, and we mean everything, in CrunchBang is accessed through a desktop right-click menu, and the organization is pretty helpful. I was fretting about how to take a time-delayed screenshot of the menu, for instance, until I saw that it could be done from the “Graphics” menu:

Peek around, and you’ll see that CrunchBang has many of the same default apps as Ubuntu and its lower-scale cousin Xubuntu. I do appreciate their default of VLC Media Player for multimedia files, because it’s one of the first things I end up changing on any new Linux install. Here’s what a CrunchBang desktop looks like with some of its default apps open (click for bigger image):

Package management is handled through the Synaptic tool familiar to any Ubuntu user. For the most part, any app that works on Ubuntu and doesn't require some specific, graphically-tied tool will work in CrunchBang. Even the tools that requires 3D compositing—like the OS X-like AWN Dock—can be used by a right-click menu switch that enable compositing (seen above).

Finally, if you’re not down with the strain-reducing black motif, or you want to change any other aspect of CrunchBang, the Openbox platform has its own configuration tool, obconf, that supports themes and tweaks lots of other stuff:

CrunchBang seems to Just Work on the two systems I tested it on, and it looks like a great fit for an on-the-go desktop for your thumb drive, or replacement for a slow-moving Linux boot. Have you tried CrunchBang and like something in particular? Refuse to give up Puppy or Damn Small Linux? Give us your reviews in the comments.






Ubuntu Pocket Guide Available as a Free Download [Ubuntu]

In the midst of the current financial crunch, the popular, free Linux distribution Ubuntu has never looked more attractive. If you’ve considered switching, a free copy of the Ubuntu Pocket Guide is the perfect place to start.

Written by Keir Thomas, author of Ubuntu Kung Fu, Ubuntu Pocket Guide and Reference covers all the beginner-to-expert knowledge you’ll need to make the move to Ubuntu.

We’ve featured excerpts from Thomas’ Ubuntu Kung Fu two times at Lifehacker, and the Ubuntu Pocket Guide and Reference offers the same level of Ubuntu expertise to anyone interested in or already living the Ubuntu life.

  • Focuses on core competencies and background knowledge needed to be an expert Ubuntu user;
  • Readable, accessible, and easy to understand—even if you’ve never used Linux before;
  • 100% new and original! Written from the ground-up to cover Ubuntu 8.04 and 8.10.

Ubuntu Pocket Guide and Reference is available from Amazon for $10, but—best of all—the book is also available as a free PDF download from the official web site. Can't go wrong with free.






Gui:config Gives Easy Access to Hidden Firefox Settings [Featured Firefox Extension]

Firefox only (Windows/Mac/Linux): Firefox extension gui:config adds an advanced settings panel with easy access to options normally hidden behind cryptic about:config options.

Once installed, the extension adds a new Advanced Settings item to the Tools menu for accessing the hidden settings.

Rather than making you install the add-on to see if the settings apply to you, we’ll just take a quick tour through all of the screens so you can visually figure out if you want to install it or not.

The Accessibility tab adds in quite a few useful settings like middle-click paste or changing the backspace key’s default setting to go back a page (an annoyance for many people).


The Browser tab gives you options to change the amount of cache being used or when the cache is checked, letting you cache more aggressively for performance reasons.


The Style tab lets you turn off Favicons, tooltips or disable blinking text (another annoyance).


The Downloads tab lets you change the download directory and adjust the alert settings for completed downloads.


The Bookmarks tab lets you configure the amount of bookmark backups that are created (usually once per day for 5 days).


The Developing tab is probably only useful for programmers, and most people won’t want to mess with these settings.


This is the type of extension that is so useful it makes you wonder why it's not included in the main distribution—they could hide it behind an advanced menu for serious tweakers only. It should be noted that not every setting is accessible from the GUI, so for certain tweaks you’ll still need to take a trip to about:config. gui:config is a free download, Firefox only.

UrlbarExt Adds Super Powers to the Awesome Bar [Featured Firefox Extension]

Firefox only (Windows/Mac/Linux): Firefox extension UrlbarExt adds 7 new buttons to the Awesome bar with a wide range of genuinely useful functionality to power up your browsing experience.

We’ve mentioned this extension before, but it has since updated with more functionality and upgraded from experimental to officially approved by the Mozilla Add-ons site (no longer requiring a login to install). The functionality of the default buttons include, from left to right:

  1. Copy the current site URL or custom formatted URL.
  2. Shorten the URL using your favorite service or right-click for more options.
  3. Search the current site using Google for the selected keyword. Right-click opens a dialog for adding keywords.
  4. Go up one level, or directly to the root of the current site with a double-click. Right-click gives you a list of levels to choose from.
  5. Tag and bookmark the current page from a menu of tags.
  6. Navigate through sequential URLs. (if the URL ends in a number, it will take you to the next numbered URL)
  7. Surf anonymously using online phproxy servers. Right-click lets you view the Google Cache along with other options.

Once installed, the settings panel lets you fully customize which icons are displayed by default or hidden behind the “Grippy”, along with a ton of other options.


Clicking on the Shorten URL button will use your default service, but right-clicking gives you extra options to email or twitter the last shortened URL, or even switch to a different URL shortening service.


The TinyURL tab in the preferences also lets you switch between your favorite service or add your own, but especially useful in this panel is the checkbox to automatically copy the shortened URL to the clipboard.


Clicking the tags button in the awesome bar will bookmark the current URL with the chosen tag, saving you from manually typing the tag each time you want to bookmark something (a pet peeve of mine).


Back in the preferences, the tags that show up in the list can be customized to your preferred set of Firefox 3 tags, and you can even configure the style of the items to put your favorite tags in bold text, for instance.


This extension is now a must-have in my toolbox just for the tag bookmarking functionality alone. Are there any extensions that you just couldn’t live without? Tell us in the comments.

Google Calendar Desktop Gadget Released [Featured Download]

Windows/Mac/Linux (All platforms): Google Desktop’s gadgets are looking more helpful these days, with the addition of an official Google Calendar gadget that puts your appointments at your fingertips.

Like the previously mentioned Gmail gadget, Google's own Calendar gadget offers quick access to straight-up GCal or Google Apps calendars, and allows for multiple instances if you're on lots of different schedules. Pull it up with the Shift-Shift tap for Desktop gadgets, and you can view your appointments in day-by-day, monthly calendar/agenda, or agenda-only view. Here's a full shot of what it looks like—while Google's blog post shows a map being drawn for location-specific items, it wasn't drawing on my screen for some reason.

Unlike the Gmail gadget, the Google Calendar Gadget runs on Google Desktop 5 for Macs and Linux, as well as Windows. It’s free, requires Google Desktop 5 and a Google Calendar account.






Speedier Ext4 Filesystem Available in Ubuntu 9.04 [Linux]

Ext4, the next-generation filesystem for Linux storage, is rolled into the latest (alpha) Ubuntu 9.04 daily builds. Considering it nearly laps its counterparts in benchmark tests by Phoronix, that could mean some nice speed-ups in handling larger files (and maybe boot-ups?) [via; graph by Phoronix]






DivFix++ Repairs Your AVI Files [Featured Download]


DivFix++ is a cross-platform .AVI repair program that rebuilds the index file within the .AVI container to restore your movie to a functional state.

DivFix++ can be downloaded pre-compiled for Windows, Mac and Linux operating systems. The interface and operation is straight forward. Tell it where you want the repaired file to be saved, drag and drop some files to be repaired into the Source Files pane of the program and let it loose. Repair time was fairly quick on my mid-level machine and the resource utilization was lower than I expected. The program required no installation, just a simple unzipping, but beyond that I can’t vouch for it’s portability. DivX++ is cross platform and open source.
